Martensitic stainless steel pipe

Martensitic Stainless Steel Pipe

Product description

Standard martensitic stainless steels are: 410, 414, 416, 416(Se), 420, 431, 440A, 440B and 440C, which are magnetic; the corrosion resistance of these steels comes from "chromium", which ranges from 11.5 to 18%. The higher the chromium content, the higher the carbon content is required to ensure the formation of martensite during heat treatment. The above three 440 types of Stainless Steel are rarely considered for applications requiring welding, and filler metals of 440 composition are not easy to obtain.
Improvements to standard martensitic steels contain additives such as nickel, molybdenum, vanadium, etc., mainly used to increase the limited allowable operating temperature of standard steels to above 1100K. When these elements are added, the carbon content also increases. As the carbon content increases, the problem of avoiding cracking in the hardened heat affected zone of the weld becomes more serious.
